Boom vs Lav - Replacing audio tracks on already edited clips Davinci Resolve

Im sharing a particular scenario where I received an edited interview with the select audio files ready to assemble with b-roll on top but I received it without the boom track sync&just the lav that went straight to camera. How did I fixed it??? Check the video out. Also some bonus audio of the finalized video with both showing the difference of boom vs lav and why it&my personal preference to use the Boom even though the lav is perfectly workable with eq'ing.
